I have a spherical container (15.5m diameter, ~2000m3 volume) that is filled with salt water at atmospheric pressure. Salinity is ~35g/litre.
At what temperature will the contents first show signs of freezing?
And.....
If ambient temperature is at the initial freezing point of the liquid, how long will it take to completely freeze the contents of the container?
Similarly, if ambient is 5 degC below initial freezing point?
This has stumped myself and a colleague for a couple of hours, so some help would be appreciated!!
Also, explanation of workings would be helpful.
Many thanks.
